Visual C++ :: How To Count Contiguous And Common Zeros In Various Arrays
May 12, 2014
If I have number of arrays(its 3 for instance and may vary) with fixed size (15), it consist of zeros and non-zeros
How to write a program to count the common zero sequences and there indexes of arrays?
eg:array1[15]={5,5,0,0,4,4,4,0,0,0,1,0,0,0,3}
array2[15]={1,0,0,0,0,7,7,0,0,3,0,0,0,0,2}
array3[15]={6,6,6,0,8,8,8,0,0,0,3,3,0,0,4}
...........
sample output for the above arrays:
Index==> Nim_of_zeros
3==> 1
7==> 2
12==> 2

So I'm trying to make two arrays, then the third array that will include common elements of those two arrays. I did make a code for that, but the problem is I don't know how to include that the elements do not repeat.
For example, if there are two arrays,
Elements of the first one: 2, 3
Elements of the second one: 2, 3, 2
The third array is going to be: 2 2
While I want it to be only 2.
#include <iostream>
using namespace std;
int* intersection(int* n1, int d1, int* n2, int d2, int& d3) {
d3=0;
for (int i=0; i<d1; i++) {
[Code] ....

4.1 Write a program that will count from 1 to 12 and print the count, and its square, for each count.
4.2 Write a program that counts from 1 to 12 and prints the count and its inversion to 5 decimal places for each count. This will require a floating point number.
4.3 Write a program that will count from 1 to 100 and print only those values between 32 and 39, one to a line. Use the incrementing operator for this program.

This is what I try to achieve:
1. Using a CScrollView as the View class type.
2. Using Document/View Architecture.
3. Insert multiple Common Controls such as CEdit, CButton, CListCtrl into the View dynamically.
4. All the Common Controls is base on a template created by user. So I do not know the quantity of the Common Controls.
This is the plan on how to do it:
1. In View OnInitialUpdate(), read the template to get all necessary info on the Common Controls to be create.
2. In View OnInitialUpdate(), create all Common Control. Some Common Control may not have WS_VISIBLE as it may not needed at initial stage.
3. In View OnUpdate(), I need to refresh the Common Control properties such as is its text, position or its visibility. This should happen if Document call UpdateAllView().
My Question:
1. Is this a normal & useable plan?
2. Do I miss other functions for any other messages?
3. Still wondering if I need to involve any coding in OnDraw() for this plan.

I have a class 'A' which is almost perfect for my needs. Class 'B' uses class 'A' I've now designed Class 'C' and Class 'D' and noticed that there is a good chunk of code in class 'B', 'C' and 'D' for using Class 'A' is duplicated. I've separated out this code in specific, standalone functions in each of the classes. Now I'm wondering where this code should go. At the moment, the functions are duplicated in the three calling classes (B, C and D). Placing the functions into class 'A' would break the single responsibility principle. Inheritance to add functionality would likely break both SRP and LSP. The one that seems that it may work is composition.
However, Is designing a complete class just for a few functions over kill?
Would it be valid for classes 'B', 'C' and 'D' to access both the new class 'E' (which would depend on A) and the old class 'A' (which would have to be the same instance as the instance in the new class 'E'), or should the new class 'E' provide sufficient functionality so that Classes B, C and D don't need to access Class A directly? It would seem that its then an incomplete interface of the original object with additional functionality (ie, incompatible) Or should I do it a completely different way?

I'm writing a program that communicates with another program over TCP/IP. I need to assemble contiguous buffers of mixed data to send to the server. For example, one of the messages must contain multiple 32-bit integers and 64-bit floats, each in its own appropriate field. I also need to receive and decode similar buffers.
The Windows TCP function "send(socket s,char *buf, int len, flags)" takes a pointer to a character array to send. Likewise, the TCP function "recv(socket s,char *buf,int len,flags)" takes a pointer to a character array to fill. I've tried creating structures describing the send and receive messages, with the fields appropriately laid out. But the CODE::BLOCKS compiler complains when I try to hand send and recv the pointers to the structure variables. Am I on the right track, or is there a better way to do this?

I am required to write a program which, when given an nxn 2D array of char, and the specified coordinates of a specific point in that array, returns thelargest number of horizontal, vertical or diagonal contiguous (side-by-side) sequence of points of that same char value that intersects with the given point.
The way I took on this problem was to:
1) First find out the number of points with the same char value up, down, right, left, north-east, north-west, south-east, and south-west of the given point.
2)Add up+down+1(the one is for the point itself), north-west+south-east+1, etc...
3) Finally I compared the four values (updown, rightleft, NESW, NWSE) and returned the largest one.
Well, that's how the program is supposed to work in theory but as you can probably guess it doesn't work. In addition to telling me what I'm doing wrong, is there a simpler way to do what I am trying to accomplish?
Here's the code:
Code:
int findLongest(char **board, int n, int row, int col)
{
char current;
int rightleft, updown, NESW, NWSE;
int r, c, c1=0, c2=0, c3=0, c4=0, c5=0, c6=0, c7=0, c8=0, d;
int t1=1, t2=1, t3=1, t4=1, t5=1, t6=1, t7=1, t8=1;
current=board[row][col];
//check Above: col remains the same
for(r=row-1;r>=0||t1!=0;r--)
//with the condition r>=0 I made sure not to accidentally check values outside of the array

How would I make the program still display zeros in front of a number?
Like say for example:
cout << "Enter any number";
cin >> number;
cout << number;
Let's say I entered 0003 as my input. How would I make it to where it will display the three zeros in front of the 3 instead of just displaying 3?

Here is an imgur link to my current homework. [URL] .....
As you can see on there I have them listed on which ones are supposed to be sentinel and which ones are supposed to be count control loops. This is currently what I have:
Code:
#include <iostream>
#include <cmath>
#include <iomanip>
#include <fstream>
using namespace std;
void main() {
int count = 0;
int sum = 0;
[Code] ....
This class has me stumped currently and I am having a hard time breezing through the class at my instructors speed. So I don't want to get too far behind.
Right now this program is giving me an error that opens CMD and gives me infinite lines of "0's".

For my assignment I have to have an array with only zeros.
Code:
int a[20] = { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 }; Then I need to send it into a function that makes the array like this
Code: int a[20] = {0,1,2,3,4,5,6, ... , 19}
Which I have done here
Code:
int initialize(int a[], int n) {
int m = 0;
int i;
printf("
[Code] ....
Now I need to do the following with the array. I need to take whatever value is in each position and add that value to all of the previous values. like this.
Code:
a[3] = a[3] + a[2] + a[1] + a[0]
only for every a[i] I know that I can code this the long way, but I just can't see to be able to find out how to do this a better way.

With the loop below, is there a way to display the actual number without the leading zeros (scientific notation) or will it just display 0 since there are so many leading zeros?
num = 1;
while (num > 0){
num /= 2;
}
cout << num;

I'm making some progress. My program does compile and output the number of line per code, but it shouldn't count comments and blank lines. I tried using (s.substr(0,2) == "//") as suggested but it didn't work.
This is my improved code:
Code:
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
const int A = 3;
int main() {
string s;

I'm new to C programming and in my first computer science class. Our assignment was to write a program that displays each digit of an integer in English. I wrote the following but cannot figure out why it won't display zeros. When I execute and type in the number 1,000, I get "zero."
Code:
#include <stdio.h>
int main (void)

How can I calculate GCF of many numbers? I thought I could calculate two by two numbers, but it not seems to be a very effective idea. There is my function:
int gcf (unsigned int x, unsigned int y)
{
return (y == 0) ? x : gcf (y, x % y);
}

Class programming project where we declare two arrays, a sting array containing the names of the boroughs and an int array which which holds accident number for each borough. The main function calls getNumAccidents() function to fill the array. it then calls findLowest() to learn which borough had the fewest accidents. It should print out the accident numbers for each borough and then out the borough and accident number with the fewest accidents.
I'm able to get the program to kind of work. When I run it everything works fine but I am not able to get the arrays to sort and match up correctly..
#include<iostream>
#include<iomanip>
#include<string>
#include<cstring>

I have been struggling with this program. I am somewhat new to c and suck at logic. I have a personal program I want to make that I will try to get extra credit for in school. I have a printed set of winning lottery numbers form the last 10 years. I chose the easiest one do do logically which is just 5 numbers none repeating.
I am trying to find out how I can print the least common 10 sets. I think if there are any set which have not been picked I would have to print all of those because logically they would all be equal, then print sequentially the sets least picked up to 10.
I have pseudocode which I am sure is wrong but will post it just to show that I am trying. My first attempt was to add the numbers but quickly realized that that wouldn't work ...
5 Nums Pseudocode
Code:
Read Nums
Parse Into Ints
Make Array [185] //39+38+37+36+35 The highest the numbers added together can go
//LOGIC
